Touch screen technology not always the best. I have a Honda HRV with touch screen controls for the radio. I hate it, you have to take your eyes off the road to change the station or raise or lower the volume. A really dumb idea on an otherwise great vehicle.

I can change volume in 3 places on my car. Knob, steering wheel, and voice command.
However, that’s not a critical system.
My steering wheel is still mechanical. There is no fly by wire here.... yet. lol
There are new cars now that use brake, throttle, gear select and even steering all by wire now.
